Sodium: it's not just about blood pressure
Vegetarian Journal, April-June, 2008 by Reed Mangels
We've all heard that reducing the amount of sodium in our diets is a way to lower blood pressure and reduce the risk of hypertension. Reducing dietary sodium also seems to have other health benefits. A large study of more than 2,400 adults who were 30-54 years old and who had high normal blood pressure examined the effects of reducing dietary sodium. Roughly half of the group was taught about ways to reduce their blood pressure, such as reducing dietary sodium, losing weight, and reducing stress. The other half did not receive this type of instruction. Ten years later, both groups were examined. Those in the group that reduced dietary sodium had a 25 percent lower risk of heart disease compared to the other group. Those eating a lower-sodium diet also had a lower risk of having a stroke, having a heart attack, and dying from heart disease.
